BAKERS ovnn.

Specification of Letters Patent.

Application filed lflovembcr 24,1919. seriai'no. 340,339.

To all whom it may concern:

Be it known that I, GEORGE L. GAY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Bakers Ovens, of which the following is a specification.

My invention relates to a new and useful improvement in bakers' oven, and has for its object to provide an exceedingly, simple and effective device of this construction by which the compartments in the oven may be heaited by the use of a minimum amount of coa A further object of my invention is to provide for transferring the bread trays to and from the oven.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawing forming a part of this application, in which Figure 1, is a perspective of an oven partly broken away and sectioned to show the interior construction thereof.

Fig. 2, is a perspective of a frame shown thereon for transfer to the oven.

In carrying out my invention as here embodied, 1 represents the oven having the heating pipes 2 so located therein as to divide the interior of the oven into compartments. Between each series of pipes is located a partition 8 of asbestos or other suitable material. i

4: represents the upper portion of the furnace from which the products of combustion arise and pass through the flue 5 the rear wheel of said flue having formed therewith the projections or baffles 6 which produce the pockets 7 The pipes 2 pass through the partition wall 8 of the oven and extend into the flue projecting partly into the pockets 7 so that when the products of combustion from the furnace travel upward they will be caused to take a sinuous course on account of the projecting ends of said pipes and the projection 6 thus impinging upon said pipes in a manner to increase the absorptionfof the heat from said products of combustion by said pipes.

TENT, orr ce.

Patented. Nov. 23,1920;

In practice I have found-that thisconstruction will transmit the 'properamount of heat to the oven at a very much less expenditure of fuel than where the flue 5 is straightaway. I

The pipes higher at the front end of the furnace than at the rear thereof and in the rear portion of the oven over each set of pipesis journaled a shaft 8 having a swinging lever '9 2 are upon, an incline being secured to, each end thereof,'one end of each of said shafts having an operating lever 10 also secured thereto, and this operating lever is connected by the rod 11 with the L-shaped hand lever 12 pivoted at the front of theoven.

13 represent tracks which are pivoted at the front end of the oven and extend rearward therefrom resting upon the ends of the levers 9 so that when the levers 9 are swung upward. to the position shown in one section of the oven in Fig. 1 the inner ends of the tracks 13 are elevated for the purpose hereinafter described.

14 represents a frame which is rectangular in shape having the tracks 15 pivoted at 16 thereto the opposite ends of these tracks being supported by the links 17 which are pivoted to the hand levers 18 which in turn are pivoted at 19 to the frame. The proper operation of the hand levers 18 will elevate the rear ends of the tracks 15 as shown in the trays and the bread carried thereby to the oven the frame 14: is rolled in front of the oven and the tracks 15 elevated at their rear ends by the proper manipulation of the hand levers 18 as before described thus giving a suflicient incline for the trays to run from ofl the tracks 15 on to the tracks 13 in the oven thus avoiding the manual handling of the trays.

When it is desired to-remove the trays from the oven the tracks 15 are returned'to the position shown in all of but one section of Fig. 2 and the inner ends of the tracks 13 are elevated as before described by the proper manipulation of the levers 12 when the trays will roll outward upon these last the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is 1. In combination with a bake oven of the character described, a portable loading frame, pairs of tracks pivoted to said frame and means for raising and lowering the free endsof each pair of tracks without affecting the other pairsiof tracks 2. In combination with a bake oven having tilting tracks therein, a portable loading frame, tracks'arranged in pairs within said frame the outer ends of each pair of tracks being pivoted to the frame, means for raising and lowering the opposite ends of each pair of tracks without affecting the other pairs of tracks, and wheel pans adapt-- ed to travel upon said tracks.

3. A baking oven comprising a series of compartments, each of said compartments having journaled "therein a shaft, swinging levers carried by each end of each of said shafts, a pair of tracks located in each compartment, the outer ends of said tracks being pivoted, the inner ends of said tracks resting upon said swinging levers, an operating lever carried by each of said shafts and means for manually swinging said operating levers for raising and lowering the inner ends of said tracks.

In testimony whereof I have hereunto affixed my signature.

GEORGE L. GAY.
